parameter transfer. When the minimum input time has elapsed and the button can be
released, OpInputMonitor indicates this with its status byte for operator input in the "Input
OK" bit.
Apart from the minimum duration, the "maximum input time" can also be set for digital inputs.
This allows a button that is sticking or defective digital inputs that supply a permanent 1
signal to be detected in good time. Such errors are once again indicated in the status byte
for operator input of OpInputMonitor, in this case in the "Input error" bit.
The two times and the code bits mentioned above are relevant only for operator input over
digital inputs.
1-out-of-n check of memory bit, DB and hardware input
For all types of operator input, in other words both for input via digital inputs as well as input
via the memory or data blocks, OpInputMonitor also returns the error status 1 out-of-n error.
It is set when TD7onTIM has detected that there is more than 1 operator entry pending
within a fast read cycle (input error):
● If there is only 1 operator entry pending, the entry will be processed and transferred.
● If there is more than one entry, the entries are rejected (double input lock).
A new setpoint or parameter is processed only when previously no entry was acquired in
at least 1 fast cycle.
If increased reliability is required for the input of commands, setpoints and parameters, all
objects with which this data is sent must be assigned to the fast read cycle (see Data
objects: Partner and send parameters (Page 198) > "Read cycle" parameter). All setpoint
and parameter objects in the fast cycle are subjected to a 1-out-of-n check; in other words, at
the end of the fast cycle there is a check to make sure that there is a setpoint or parameter
entry for only 1 of the acquired objects.
Note
Resetting the input bits
•
If entries are made via a memory or data byte, or a setpoint or parameter entry is enabled
by a memory or data bit (via the send trigger "Triggersignal"), the set entry bit or trigger
signal is automatically reset to zero by TD7onTIM.
If, however, a 1-out-of-n error is detected, the bit is not automatically reset. You then
need to reset the input bit manually or have it reset by the user program.
